 * Spread text over cells:
 * Spread a Textflow over several cells.
 * 
 * Create a simple table with a Textflow which is spread over several cells. Use
 * the "continuetextflow" option of add_table_cell() for each Textflow cell the
 * Textflow is to be spread over. 
 *
 * Required software: PDFlib/PDFlib+PDI/PPS 9
